Computer programming is one of the fastest growing field. If you are a programmer then you can be hired by a top tech company or you can also work as a freelancer and earn decent amount. So the question arises, how to learn to code ? Initially it was very difficult to learn programming. As there was no internet and you have to relay on books or your colleagues’ code. Now you can find tons of material on the internet. You can learn any computer programming language you want. I am going to tell you some sites which you should visit regularly.

Huffman Code compress data very effectively: saving of 20% to 90% are typical, depending on the characteristics of the data being compressed.Huffman's greedy algorithm uses a table giving how often each character occurs (i.e., its frequency) to build up an optimal way of representing each character as a binary string. This algorithm constructs an optimal prefix code called a Huffman Code.

What is namespace?"In general, a namespace is a container for a set of identifiers Namespaces provide a level of direction to specific identifiers, thus making it possible to distinguish between identifiers with the same exact name. " Or According to Wikipedia “In computer programming namespaces are typically employed for the purpose of grouping symbols and identifiers around a particular functionality and to avoid name collisionsbetween multiple identifiers that share the same name.”
